Actually, the "s" value (speed setpoint) IS being trimmed via an analog input (\74) whose range is 0 to 200, hence the calculation \66={s*(\74/200)}. The trim pot is assigned to variable \74 in the CNCSETUP.
And, as you suggest, I am already using a display to show the "s" value. Since it is static, it displays well.
Now if I can just get that darned gauge to work....
